I don't mean to intrude but I also have a question about iCloud Drive and app support.
I still have my iPad on 7.1.2 bc it's jailbroken. If I upgrade my 6 to iCloud Drive, will apps that I use on my iPad no longer sync between my phone and my iPad?
Examples: games such as boom beach, World Series of poker and apps like 1password and anything else that syncs between devices.
I'm usually pretty intelligent on these matters, but on drive I'm rather out of touch.
